Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A general name for a lump - bump - or other projection on a bone; can be articular processes or nonarticular processes - which are usually sites where tendons attach.






2. Skull bones; external bones of the cranium. These bones make up the 'forehead' region of the skull and contain the large frontal sinuses. The cornual process in horned animals is an extenion of this bone.






3. One of the three ossicles in the middle ear; also called the hammer - this bone is the outermost of the three ossicles and is attached to the tympanic membrane.






4. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






5. The collective name for 37-38 bones of the head; it houses the brain and all the special sense organs.






6. The visceral bone in the heart of cattle that helps support the valves of the heart.






7. Another name for cancellous bone.






8. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






9. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






10. A longitudinal ridge on the front of the proximal end of the tibia.






11. The 'forearm' region of the thoracic limb.






12. A large channel through which large blood vessels pass carrying blood to and from the bone marrow.






13. A pair of large holes in the pelvis located on either side of the pubic symphysis; the role seems to be to lighten the pelvis because no large nerves or vessels pass through them.






14. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






15. A bone of the sternum.






16. The vestigial metacarpal and metatarsal bones of a horse's leg. There are two spint bones in each leg: one on either side of the cannon bone (MC/MT III). The medial bone is MC/MT II and the lateral bone is MC/MT IV.






17. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






18. The large hole in the occipital bone through which the spinal cord exits the skull.






19. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






20. The long bone of the brachium or upper arm.






21. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






22. The joint movement whereby an extremity is moved away from the median plane.






23. The single - dorsally projecting process of a vertebra.






24. The outer layer of a bone that is composed of compact bone.






25. The joint composed of the carpal bones; referred to as the 'knee' of the horse and the 'wrist' of humans.






26. The most caudal of the three pairs of bones that make up the pelvis.






27. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






28. Bones formed in the soft organs (viscera); examples include the os penis - the os cordis - and the os rostri.






29. The joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans.






30. The long bone of the thigh region; it forms the hip joint with the pelvis at its proximal end and the stifle joint with the tibia at its distal end.






31. Another term for the diaphysis of a long bone.






32. A flat articular surface - such as between carpal bones and between the radius and ulna.






33. The cartilaginous ventral portion of a rib.






34. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






35. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






36. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






37. Incoordination; animals with this make jerky - spastic movements.






38. The large metacarpal and metatarsal bones (III) of the horse.






39. Large - multinuclear cells of bone that absorb bone and structures and reshape or remodel damaged bones.






40. A rib whose costal cartilage joins the costal cartilage of the rib ahead of it instead of directly joining the sternum.






41. A bone whose shape does not fit into the long bone - short bone - or flat bone categories. Bones either have characteristics of more than one of the other three shape categories or have a truly irregular shape. Includes vertebrae and sesamoids.






42. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






43. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






44. The bones along the central axis of the body; made up of the skull - hyoid bone - the spinal column - the ribs - and the sternum.






45. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






46. The thin layer of hyaline cartilage that covers the articular surfaces of long bones in synovial joints; it forms a smooth layer over the joint surfaces of the bones - which decreases friction and allows free joint movement.






47. Short - faced; breeds including Boston terriers - pugs - English bulldogs - and Pekingese.






48. Mature bone cells located in lacunae.






49. The joint movement that decreases the angle between two bones.






50. The joint movement that increases the angle between the two bones.
